Applicatiorrfiled March 20,1891. Serial No. 385,933. (No model.) Patented in France May 6,1879,No.130,518; iuEnglalid January 2, 1891, N0. 76 i in Austria-Hungary February 7,1891, No. 7,592 and No. 22,875, and in Germany February 24, 1891.

To all whom it may concern: Be it known that L'LEON LETALLE, a citizen of the French Republic, residing at Beauvais,-in the Department of the Oise and Republic of France, have invented an Improvementin Looms for Weaving Chenille Intended for the Weaving of Carpets and other Chenille Fabrics. (for which Letters Patent were granted in France May 6, 1879, No. 130,5l8; in England January 2, 1891, No. 75; in Austria-Hungary February 7, 1891, N 0. 7,592 and No. 22,875, and in Germany February 24, 1891,

No. 58,288,) of which the following is a speci-' fication.

The manufacture of long-pile carpets with chenille weft is eflec'ted by ordinary means as follows: Each Weft-thread of chenille is made beforehand and is composed ofas many points of different colors as requiredby the design or pattern. To obtain this result a fabric is woven composed of warp-threads set wide apart, and these threads serve to bind spaces between the warp-threads.

the woolen weft-threads, which are each of the color required by the pattern. After the weaving this fabric is divided into strips or bands by cutting the weft-threads along the Each of these out threads of chenille will result in a part or point of the design of the carpet, and the entire strip or band will serve as weft for its composition. The order in which these wefts of chenille are placed in the Weaving of the carpet determines the arrangement of the pattern.

Weaving lo1'1g-pile fabrics by hand occupies much time by reason of the large num ber of shuttles to be worked.

The loom forming the subject of this invention has for its object the mechanical weaving of the fabric for the chenille wefts by dis pensing with the shuttles and replacing them by a single pincher r nipper having an analogous to-and-fro motion, and which at each movement seizes and carries a weft-thread through the shed. Therefore to obtain the variety of color given by the several shuttles it is only necessary to present a diiferent I thread to the nipper at each of its movements,

this result being produced by the distributor with keyboard placed on the left-hand end of the loom:

My invention is illustrated in the accompanying drawings, in which- Figure 1 shows in detail the chenille web, which is cut apart to produce weft-threads. Fig. 2 is a side view of a loom having applied thereto the distributer embodying my invention. Fig. 3 shows one side of the 100m, the distributer and manner of fixing it thereto, and the box containing the bobbins of Wool. Figs. 4 and 5 are enlarged detail views of parts'of this distributer. view of the nipper. Fig. 6 is an end view of same. Fig. 7 is a plan view of the nipper and shears. Fig. 8 is a side view of the shears,

showing the manner of attaching them to the batten-arm X. Fig. 9 is a front view of the entire loom. Fig. 10 is a front view of the distributer, to the keyboard. Fig. 11 is a sectional plan view taken on the line X Y of Fig. 10. Fig. 12 is a sectional view taken on the line 71. n of Fig. 10, and it also shows the box containing the bobbins 0.. Figs. 13, 14, and 15 are details of the various parts of the distributer. Fig. 9 is a general view of the loom and distributer and a good idea of the arrangement Fig. 6 is a side showing the working connections and relation ofthe various parts will be 013- I tained from an inspection of it.

D is the distributer. Y is the stationary frame of the loom.

X is the batten-frame, which carries the guide G for the needle N and needle-bar T.-

H is a support for the needle, fixed to the Ioomframe by a brace 12'.

The batten is operated by the crank-shaft .2, connections .2 z, and bar b which is fixed to the batten-frame X X. The needle N is reciprocated by the eccentric V and spring R through the rods 1" r 1 A latch X is provided to hold the needle N, stationary in the support H while the batten X is making its beat. This latch is operated by the smalleccentric 41 which is placed upon the same shaft with the large eccentric V A revolution of the twoeccentrics will operate as fol will depress the,

lows: The small eccentric '0 rod r5, which will'draw, down the rod r and lift the latch X which will be returned to ts posit-ion by the sprin 5 At the same time the revolution of "he eccentric V will throw back the rod '2", which will pull the rod 1' which will draw back the rod r, which in turn will throw the ne-zzdlc-l.aar T and neodle N. This movement will alternate with the beat of the batten, as in ordinary looms.

The construction and operation of the distrlbuter and its relation to the parts of: the 100m will be now described.

An inspection of Figs. 2, 3, and 9 wills-how that the distributor is attached to the stationary frame Y of the loom by a bran .ct or casting Z, upon which is also carried the keyboard K.

The various detail parts of the distribute-r assembled in operative position and their rclation to each other will be more clearly seen by reference to Figs. 1,0 and 15 and also Figs. and Asseen in Fig. 10, Z is a circular casting bored io'receive the liieariugs oi. the 'i iivois l 2 5 6, rise. Each of these pivotshas a sec tor C, of thin sheet-iron, at one end and at the other a grooved pulley c, Fi 3. This pulley c, Fig.15, is not entirely circular, but is of semicircum t'ercntial form so as to occupyless space and to permi the superposition of a greater number of them. Each of the pulleys c connected by a cord d to a bell-crank lever E, forming a key, as in a piano. The cord is fixed to the pulley 0, but extends beyond to an anchorage a. An adjusting-spring D,in terposed in the length of the cord, keeps the key in its place. Each of the cords d passes over one of the return-pulleys c. When the operator desires to bring a color to the point 0, he presses upon the corresponding key,

(which custom teaches him quickly.) The kcyE takes the position Fig. i l. The ten-- sion which it operates upon the cord (1 causes the half-pulley with groove 0 to pivot. This pivots the axle upon which one of the sleeves is fixed. This lowers the sector 0, and it takes the position represented in Fig.10. The tube B, which terminates it, is then facing the nipper of the loom and has carried the desired thread there. On releasing the key the spring D-brings back the pulley c, the sector C, and the lever E, and the key resumes its normal position. A stop-rod 10, Figs. 10 and 14, limits the position of the'bent lever E, which, be ing always acted upon by the spring, constantly rests upon it. The workman thus changes color by working this or that key, which brings the tube carrying the thread of wool to the center of the apparatus.

At section, Fig. 12, it will be seen that each of the sectors, being independent, may be displaced with facility. Then being set upon axles of diifercnt lengths permits them, in superposing, to slide the one behind the other. Their sector shape permits them to carry the tube to the center without being an obstacle.

The lay or batten X is furnished with a toothed guide G to receive and guide a ripother with considerable force.

the other tubes 3 per N, which is constructed as follows: Two steel jaws ff, Figs. 6 and 7, are fixed upon a metal part or head F. These jaws are of spring metal and tend to close upon each A cam G, having a linger 1 attached to it bywhich itis operate-fl. is pivoted between the jaws ff. The cam G is turned at one end of the throw oi the needle N by the linger coming in contact with the finger 'v on the batten and at its opposite end of the throw by the finger I, also upon the batten.

The shears which cut the it is tightened up by the batten are constructed. of an arm or blade Ii, fixed to the battcnframe X, and a in able arm or blade M,pivotcd upon the fixer ll-lflllTJ. A springblkecps the arms normally apart. Mounted upon the arm is a roller m, which at each stroke of the batten comes in contact with. the roller Q Jpon the loom-frame '3, contactwith which will force the arm llij down upon the arm L and cut the Weft-thread. The shears are do plicated at the other end of thebattcn,tl1cre being this difference, that the shears at the right do not out, but merely lake the Weftthread from the nippor and hold it taut, so that it may he dri ven into place by tl'iobatten.

The working of this loom is exceedingly simple. 'Wluzn the operator has chosen the thread it" rich is required, be war... the corresponding key, which brings the tube l; to the center 3 at, the moment that the batten is at its backward position. At this int" iii the eccentric V actuatcs th i" described, which comet r as onto the tube 13, and then permit .d to close by the tin ger g coming into contact with the li" r, and thereby turning the cam 5?. At this moment the eccentric V has made a haltrevolution, and no longer acting on the counecting-rods the spring iii? brings the nipper backward, and at the same time this latter draws the woolen thread through the warp. The batten or lay X then makes its forward movement to beat up this weft of wool. Before reaching the end of its journey the roll-- ers m of the shears carried by the batten strike against the rollers Q and the shears close. Those on the left, which are cutting, produce the section of the woolen thread, which thus finds itself separa ed from the tube ll, but nevertheless held by the shears, which nip at the same time that they cut. Those on the right, which are simply ni pping, hold the woolen. thread. Just before ending its journey the batten brings the latch 5 against the strikin g pieces or steps R, which release the shears,

permitting them to open, thus releasing the woolen thread and permitting the batten to tighten it up. At the same time the rod t,

on the small which it causes to pivot in order to The batten then retires to seize another which is fixed to the batten, acts cam G, open the nipper. permit the nipper to return and thread.
